| 1 | Power management unit chip design for automobile active-matrix organic light-emitting diode display module显示文摘A power management unit (PMU) chip supplying dual panel supply voltage, which has a low electro-magnetic interference (EMI) characteristic and is favorable for miniaturization, is designed. A two-phase charge pump circuit using external pumping capacitor increases its pumping current and works out the charge-loss problem by using bulk-potential biasing circuit. A low-power start-up circuit is also proposed to reduce the power consumption of the band-gap reference voltage generator. And the ring oscillator used in the ELVSS power circuit is designed with logic devices by supplying the logic power supply to reduce the layout area. The PMU chip is designed with MagnaChip’s 0.25 μm high-voltage process. The driving currents of ELVDD and ELVSS are more than 50 mA when a SPICE simulation is done. | KIM J H PARK J H KIM J H CAO T V LEE T Y BAN H J YANG K KIM H G HA P B KIM Y H | 2009 | Journal of Central South University2009，16，4： | 4 |
| 2 | Abnormal liver chemistries as a predictor of COVID-19 severity and clinical outcomes in hospitalized patients显示文摘BACKGROUND Abnormal liver chemistries are common findings in patients with Coronavirus Disease 2019(COVID-19).However,the association of these abnormalities with the severity of COVID-19 and clinical outcomes is poorly understood AIM We aimed to assess the prevalence of elevated liver chemistries in hospitalized patients with COVID-19 and compare the serum liver chemistries to predict the severity and in-hospital mortality.METHODS This retrospective,observational study included 3380 patients with COVID-19 who were hospitalized in the Johns Hopkins Health System(Baltimore,MD,United States).Demographic data,clinical characteristics,laboratory findings,treatment measures,and outcome data were collected.Cox regression modeling was used to explore variables associated with abnormal liver chemistries on admission with disease severity and prognosis RESULTS A total of 2698(70.4%)had abnormal alanine aminotransferase(ALT)at the time of admission.Other more prevalent abnormal liver chemistries were aspartate aminotransferase(AST)(44.4%),alkaline phosphatase(ALP)(16.1%),and total bilirubin(T-Bil)(5.9%).Factors associated with liver injury were older age,Asian ethnicity,other race,being overweight,and obesity.Higher ALT,AST,T-Bil,and ALP levels were more commonly associated with disease severity.Multivariable adjusted Cox regression analysis revealed that abnormal AST and T-Bil were associated with the highest mortality risk than other liver injury indicators during hospitalization.Abnormal AST,T-Bil,and ALP were associated with a need for vasopressor drugs,whereas higher levels of AST,T-Bil,and a decreased albumin levels were associated with mechanical ventilation CONCLUSION Abnormal liver chemistries are common at the time of hospital admission in COVID-19 patients and can be closely related to the patient’s severity and prognosis.Elevated liver chemistries,specifically ALT,AST,ALP,and T-Bil levels,can be used to stratify risk and predict the need for advanced therapies in these patients. | Arunkumar Krishnan Laura Prichett Xueting Tao Saleh A Alqahtani James P Hamilton Esteban Mezey Alexandra T Strauss Ahyoung Kim James J Potter Po-Hung Chen Tinsay A Woreta | 2022 | World Journal of Gastroenterology2022，28，5： | 2 |
